Resources for Turkish NLP Resources

Interestingly, I and both of the resource aggregators are from the same high school, i.e. Izmir Fen Lisesi :-)

Will maintain my own list upon these. I forked (copy-pasted) and combined their lists below.

My Blog:

  • Social Network Analysis and Data Mining (SoNADaM). Although the lab name does not include NLP or text in it, publications listed on their page should justify my decision to have them here.
  • Arzucan Ozgur (used to be my TA) (Turkish polarity seed words list will be expanded in two-three months)

Turkish morphology test files, second one includes ambiguous parses (the first parse on each line is correct). The data is hand tagged, it has good accuracy.

Turkish English parallel text from Kemal Oflazer, Statistical Machine Translation into a Morphologically Complex Language, Invited Paper, In Proceedings of CICLING 2008 — Conference on Intelligent Text Processing and Computational Linguistics, Haifa, Israel, February 2008 (lowercased and converted to utf8). The Turkish part of the dataset is “selectively split”, i.e. some suffixes are separated from their stems, some are not. is the Turkish text used to develop the language model.
